Omnidirectional swing angle detection mechanism and measurement method of double-sling bridge crane

Abstract

The invention uses a double-sling bridge crane omnidirectional swing angle detection mechanism and measurement method, so that the measurement of a space angle can be directly measured without angle decomposition, and proposes a rolling contact variable resistance measurement method for the circumference angle measurement And a measurement method based on the photoelectric effect, through which the measurement of the angle can be realized, especially in cooperation with the device to easily complete the measurement of the spatial angle. Compared with the existing technology, this structure is relatively simple, low in cost, green and pollution-free, easy to implement and easy to maintain, good in real-time, high in conversion efficiency, accurate in measurement, does not need to perform a large number of calculations, does not need to build multiple measuring devices, and is resistant to The interference ability is extremely strong, which meets the actual needs of bridge crane swing angle measurement.

Description

technical field [0001] The invention relates to the fields of optics, electrical equipment and electrical engineering, and measures the swing angle of a suspension rope of a bridge with double spreaders. Background technique [0002] With the deepening of globalization and the continuous development of world trade, the rapid development of the container shipping industry has been driven. The scale of the port is also continuously expanding. As the key equipment for container operations in the port, the bridge crane's working capacity determines the cargo handling capacity of the terminal. The double spreaders of the double lifting bridge crane can load and unload two different containers at the same time, which greatly improves the transportation efficiency of the container terminal. However, due to some practical reasons (equipment loss, friction between equipment) and external environment and other factors during the operation, the load swings. The movement of such a cra...
